The Freud 10 mm Diameter Through Hole Bit (TH10070L) is an industrial-grade carbide tipped boring bit engineered for precision drilling on multiple spindle machines. With a 70mm overall length, a 10mm shank fitted with an adjustable top screw, and a 60 deg. point angle that guides the bit to an accurate hole location, this bit delivers clean, repeatable through holes in a wide range of materials - from hardwoods and softwoods to veneered plywood, composites, and solid surface. Left-hand rotation makes it the right match for compatible boring machine setups requiring LH bits, and Freud backs it with a Limited Lifetime Guarantee for long-term confidence in your tooling investment.

Key Features

• Industrial carbide tips - provide superior cutting performance and extended tool life compared to standard steel bits, reducing bit replacement frequency on demanding production runs.
• 60 deg. point angle - ensures accurate hole location when drilling through holes, minimizing wandering and improving hole-to-hole consistency across multi-spindle setups.
• 10mm shank with adjustable top screw - makes the bit compatible with most boring machines, simplifying setup and reducing the need for adapters or special tooling.
• Left-hand (LH) rotation - designed specifically for left-hand spindle configurations, ensuring proper chip evacuation and cutting geometry for clean results.
• 35mm maximum hole depth - provides sufficient boring capacity for standard through-hole applications in panels and sheet goods.
• Freud Limited Lifetime Guarantee - reflects the brand's confidence in the durability of this bit, giving buyers long-term protection on their tooling investment.
• Made for multiple spindle machines - compatible with both automatic and manual multi-spindle boring machines, as well as drill presses and hand held drills for versatile shop use.

Why This Product

• If your operation requires consistent, accurate through holes across panels of hardwood, softwood, veneered plywood, or composite material, the 60 deg. point angle and industrial carbide tip work together to deliver reliable hole placement run after run.
• The 10mm shank with adjustable top screw means this bit drops into most multi-spindle boring machines without modification - saving setup time and keeping production moving.
• Left-hand rotation is a specific requirement for many boring machine spindles, and this bit is purpose-built for those configurations rather than being a generic drilling solution.
• Freud's Limited Lifetime Guarantee means this is a long-term tooling investment, not a disposable bit - industrial carbide construction is designed for superior performance and maximum life in production environments.

Frequently Asked Questions

What machines is this through hole bit compatible with?

This bit is designed for multiple spindle machines, including both automatic and manual multi-spindle boring machines. It is also compatible with drill presses and hand held drills. The 10mm shank with an adjustable top screw makes it compatible with most boring machines without the need for special adapters.

Why does this bit use left-hand (LH) rotation?

Left-hand rotation is required for certain spindle configurations on multi-spindle boring machines. The TH10070L is specifically engineered with LH rotation to match those setups, ensuring proper cutting geometry and clean chip evacuation. Always verify your machine's spindle rotation direction before selecting a boring bit.

What materials can this Freud boring bit drill?

This bit is suitable for drilling composites, solid surface materials, veneered plywood, hardwoods, and softwoods. The industrial carbide tip is built to handle the range of materials commonly encountered in cabinet, furniture, and millwork production.

What does the 60 deg. point angle do?

The 60 deg. point angle is designed to provide accurate hole location when boring through holes. This geometry helps guide the bit precisely at the start of each cut, improving consistency and reducing the risk of the bit wandering - which is especially important in multi-spindle applications where hole-to-hole alignment is critical.
